Excellent value - Midwest Industries T1/T2 Red Dot Optic Mount

At about half the price of some other models, it can't be beat. Very well built, attention paid to the small details (steel thread inserts where the bolts tighten), and simple. No built-in rear sight, which I prefer, just a fairly big window to look through if you need to use your irons. I have a romeo4 xt pro on mine on top off a BCM 14.5, and it's a perfect setup.
